What is considered a high explosive?
High Explosives – explosive materials that can be caused to detonate by means of a blasting cap. A few examples of high explosives would be boosters, detonators, dynamite, water gels/slurries, and emulsions .
What are 2 types of high explosives?
- 1 – blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
- 2 – perforating explosives (intended for use in the oil and gas well industry);
What is C4 made of?
C4 is composed of RDX (91%) , dioctyl sebacate (5.3%), polyisobutylene (2.1%), and mineral/motor oil (1.6%) [1].
What is a Class 4 explosive?
Class 4 – Flammable solids ; Substances liable to spontaneous combustion; Substances which, on contact with water, emit flammable gases. Division 4.1 Flammable solids, self-reactive substances and solid desensitized explosives.
What are the 9 DOT hazard classes?
A visor card guide for state and local law enforcement officials illustrating vehicle placarding and signage for the following nine classes of hazardous materials: 1) Explosives, 2) Gases, 3) Flammable Liquid and Combustible Liquid, 4) Flammable Solid, Spontanaeously Combustible and Dangerous When Wet 5) Oxidizer and ...
What is considered a Class 1 explosive?
341.11 Class 1 Divisions
Division 1.1 consists of explosives that have a mass explosion hazard . Examples are black powder, nitroglycerine (desensitized), dynamite, most types of torpedoes, and mercury fulminate.
What is a Class 2 explosive?
An explosion class 2 is a location in which combustible dusts may be present in sufficient quantities , either in suspension, intermittently or periodically, to produce ignitable mixtures.
What are the examples of explosive?
Examples include primary explosives such as nitroglycerin that can detonate with little or no stimulus and secondary explosives such as dynamite (trinitrotoluene, TNT) that require a strong shock (from a detonator such as a blasting cap). Low explosives change into gases by burning or combustion.
What is a 1.6 explosive?
1.6 Explosives
Materials classified as 1.6 materials that are extremely insensitive that do not have a mass detonation hazard . These materials are less dangerous than materials classified as 1.5 in that they have an even less change of accidental detonation or ignition.
Can dynamite explode without a blasting cap?
Crystals will form on the outside of the sticks, causing them to be even more sensitive to shock, friction, and temperature. Therefore, while the risk of an explosion without the use of a blasting cap is minimal for fresh dynamite , old dynamite is dangerous.
Which is the most explosive?
- TNT. One of the most commonly known explosive chemicals is trinitrotoluene, or TNT, which has featured extensively in video games and films. ...
- TATP. ...
- RDX. ...
- PETN. ...
- Aziroazide azide.
What is high and low explosive?
Low explosives are mixtures of chemicals that burn very rapidly, but subsonically (as opposed to supersonically), meaning that they “deflagrate.” They consist typically of fuel and an oxidizer. ... High explosives do not need to be contained to make their bang. Nitroglycerine, trinitrotoluene, and RDX are high explosives.
